Lever Principle in Physics: Diagram and Real-World Application #161460 (License: Personal Use)

The left side displays a simplified lever diagram with effort force (P), fulcrum (triangle), load (W), and reaction force (F). The right side shows a man pushing a wheelbarrow carrying a child, where the wheel acts as the fulcrum, the child’s weight as the load (W), and the man’s push as the effort (P), illustrating first-class and third-class lever dynamics in daily life.

Used in educational physics resources, STEM lesson plans, or introductory mechanics articles; targets students and educators seeking visual explanations of simple machines and torque concepts.
